newsitem {2011-November-01} {Version 3.7.9} {
  SQLite [version 3.7.9] is a regularly scheduled maintenance release.
  Upgrading from version 3.7.6.3, 3.7.7, 3.7.7.1, and 3.7.8 is optional.
  Upgrading from other versions is recommended.

  The [SQLITE_ENABLE_STAT2] compile-time option is no a no-op.  The enhanced
  query-planner functionality formerly available using SQLITE_ENABLE_STAT2
  is now available through [SQLITE_ENABLE_STAT3].  The enhanced query planning
  is still disabled by default.  However, future releases of SQLite might
  convert STAT3 from and enable-option to a disable-option so that it is 
  available by default and is only omitted upon request.

  The [FTS4] full-text search engine has been enhanced such that tokens in
  the search string that begin with "^" must be the first token in their
  respective columns in order to match.   Formerly, "^" characters in the
  search string were simply ignored.  Hence, if a legacy application was
  including "^" characters in FTS4 search strings, thinking that they would
  always be ignored, then those legacy applications might break with this
  update.  The fix is simply remove the "^" characters from the search 
  string.

  See the [version 3.7.9 | change summary] for additional changes associated
  with this release.
